  • Carbonate buffers - ETH Z

    Carbonate buffers Theory A classic buffer is a combination of a weak acid and its conjugate salt; for instance, carbonic acid (H 2CO 3) and sodium bicarbonate (NaHCO 3), or even sodium bicarbonate and calcium carbonate. What happens when you titrate this combination with the (strong) acid of your choice? Well, in any buffer system, the boost in

    Sodium bicarbonate buffer systems are made by mixing solutions of sodium carbonate and sodium bicarbonate. Take Care of and Use the pH Meter Correctly. The use of pH meters seems almost intuitive; however, pH meters must be maintained properly and electrodes cleaned and filled, and pH calibration buffers need to be correctly prepared and free of contamination.

  • PH buffering: Bicarbonate - OpenAnesthesia

    The human body has four native buffer systems – bicarbonate, hemoglobin, protein, and phosphate systems. An ideal buffering system has a pKa of ~ 7.4 (normal physiologic pH). Bicarbonate has a pKa of 6.1, which is NOT ideal in normal physiologic conditions. In fact, the pH range of effectiveness is probably ~ 5.1 – 7.1 for the bicarbonate buffer system.

    Sodium cacodylate buffer [Na(CH3)2 AsO2 • 3H2O] is a alternative to Sørensen’s phosphate buffer. It has good pH buffering capacity within the range of pH 5.0–7.4. Cacodylate was introduced for electron microscopy applications by Sabatini et al. (1962) as a method of avoiding adding additional phosphates to sample preparations. Mitochondria and other organelles can be damaged when ...
